This show wants to be everything at once - drama, comedy, isekai, harem, battle anime - and fails at doing any of the genres well.
First of all there's the obvious issue of the story referencing a bunch of stuff that is never explained to viewers and which, I assume, only makes sense to those who played the game and read the manga or light novel or whatever the basis is.
Secondly, the whole thing is just so boringly generic and predictable and huge chunks of the main story arc makes no sense at all. Especially the Karyl character is just terribly conceived.
Thirdly, in the last 3 episodes they introduce like 70 new characters without explaining who they are and where they come from and stuff the story so full of false endings and mythology grabbed out of thin air, that I was loudly begging for it all to just end already.
The only thing Princess Connect! Re:Dive has going for it is a few mildly amusing running gags. It should have stuck to being comedy and quit the whole drama thing, because it doesn't work, it's predictable and we have seen it all a gazillion times before, but rarely so incompetently done.
This is garbage.
